Be it known that I, THoMAs F. PAYNE, residing at Pittsbur h, in the county of Alleheny and State 0 Iennsylvanitn'a citizen 0 -the United States, have invented ordiscovered pertain new and useful Im rovements in Frost-Proof Water-Oloset alves, of which improvement the following is a specification. I

My invention relates to improvements in water closets, and has particularly to do with the construction of the valve controlling the'flushing flow of water. The construction is such that, though the closet be installed in 'a" lace ossessing the temperature of the out oor air, thecontrolling valve may be placed in the. ground beneath the frost line, or m some other adjacent protected place, to the end that the water in the valve ma never freeze.

A further eature is that the pipe throu h which the flushing stream is conveyed tot e closet \is, except during operation, kept empti, and is not subject to stoppage or 'mjuil'y y freezing.

n the accompanying drawing? which form part of this specification, igure 1 shows 1n side elevation the water closet and the pipe connections; and Fig. 2 is a vertical section of a flportion of the a paratus, illustrating the ushing valve an its operation.

Referring to the drawings, the bowl of the closet is shown at 1, with a pipe connection 2 for the flushing stream of water, a discharge to soil pipe 8, and a seat, 4. The controlling valve for the flushing stream is located in the casin 5 beneath the surface of the ground or in 0 her convenient and protected place, preferablydirectly beneath a pipe connection upon the flushing pi e 2.

his valve casing 5 connects with the ushirg pipe 2, through a connecting pipe 6. In a dition to the connectingpipe 6 the valve casing 5 is provided wit an inlet pipe 7 and an outlet pipe 8.

The valve is composed of three valve parts, 9, 10, and 10*, ri 'dly carried upon a common stem 11. he valve part 9 moves with the movement of the stem to control communication from the chamber of the valve casing to the connecting ipe 6.

The valve stem 11 is hollow, and'a ords a passageway of relatively small size from connectingpipe 6t'o the outlet its seat, as

I pipe 8 from thevalve casing, .when the valve 11s in inopera-' tive positzoa'with the valve 9 on racer-racer whrnreonos'nnvsnvn.

the middle section, a. e., bet-ween valve parts 10 and 10"-the passa eway through the valve stem 11 opens. When the valve is in the inoperative position indicated in Fig. 4 communication is open from connecting pipe (3 through valve stem 11 to out-let pipe 8. Rise of the valve (which, as above explained opens communication through valve part 9 from the inlet pipe 7 to connecting pipe 6) effects closure of communication to outlet 8 by valve part 10 assing over the orifice to said outlet pipe. alve part 10 at all times separates inlet 7 from direct communication through the valve chamber with outlet 8.

The seat 4 of the water closet is hinged. One arm of a lever 16, mounted on a fixed fulcrum (which is conveniently carried by the connecting pi e 2, as shown), extends beneath the hinge seat 4, and the opposite arm of the lever is held in desired normal position fromwhich it may be swung in one direction against the tension of a spring 12. In its normal position, the lever sustains the seat 4 in the slightly elevated position indicated in the drawings; and when the seat is depressed by the user the lever swings against the tension of the said spring; and the spring again causes the seat to rise when pressure is removed from the seat. The tension of the spring 12 is conveniently exerted between a rigid plate 13 and a block 14, which block is carried on a rod 15 connected in turn to the arm oi. lever 16. Connection is also maintained from the hinged seat to the fiushin valve, and this is preferably effected by pro onging the rod 15 throu h an imperious diaphragm 17, continuing it through the connecting pipe 6 and uniting it in rigid connection with valve stem 11. The discharge pipe 8 from the valve casing may conveniently be continued to the soil pipe 3, as is indicated in Fig. 1.

Re erring now to Fig. 2, it will bu observed that, when the user sits upon the seat and depresses it, the valve art 9 will be raised from its seat and a ushing stream will pass from the valve chamber through the connecting pipe 6 and the flushing pipe 2, and will continue to flush the closet so long as the user sits upon the seat. At the same time the normal communication through valve stem 11 between pipe 6 and outlet 8 is'cut off. When the weight isremoved from the seat, the spring 12 will cause the seat'to rise again, and :will shift the valve part 9 back toits seat and so shut off the flushing stream. At the same time communicating through valve stem 11 will again open, and the water then remaining in the connecting pipe 6 and in the flushing pipe 2 will escape through outlet 8 to the S011 pi e.-

It will be observed that the valve within casing 5 is a balanced valve, undisturbed ,fwhen in inoperative osition by-any fluctuation ofpressure in he water supply pipes; and that by virtue of its structure its movements are readily controlled by such a spring as is indicated at 12 in the drawings.

-Itwill be apparent that not only is the operatin valve thus placed beyond the reach 0 the frost but that the pipe connections are draine of water when the closet is not in use, and so there is no possibility of freezm1 I claim erein as my invention:

A valve-structure for controlling the flow of water from a source of water supply to auwater-closet, or like fixture, such structure I consisting of a cylindrical valve casing having a lateral inlet and an outlet in one head thereof, the said outlet controlled by a valve copies 0! this patent may be obtained to opening in the direction of'flow, a drain orifice openin laterally from said cylin- %he"a'foresaid water inlet being arranged intermediate between such drain orifice an'd the aforesaid outlet, a twoart iston valve arranged within said cyindrieal valve chamber and mounted on a common stem with the first mentioned outlet valve, and a by-pass extending through such valve stem and maintaining communication from the discharge side of the first named outlet valve to the chamber formed by and between the members of said double piston valve, one member of said double piston-:valve maintaining in all operative positions a closure between the said inlet orifice and the said drain orifice, the other of said piston valve parts assing in its range of motion across said ischarge orifice, and the said casin orifice an forming a closed pocket beneath the said valve-provided stem substantially as described.

In testimony whereof, I have hereunto set my hand.
